Minimum Cost Estimation of a Baseline Survey for a Molecular Epidemiology Cohort Study: Collecting Participants in a Model Region in Japan.
Journal of epidemiology, 2016Co-Authors: Izumi Mishiro, Norie Sawada, Motoki Iwasaki, Kayo Ohashi, Shoichiro TsuganeAbstract:BACKGROUND Some recent molecular epidemiology studies of the effects of genetic and environmental factors on human health have required the enrollment of more than 100 000 participants and the involvement of regional study offices across the country. Although regional study office investigators play a critical role in these studies, including the acquisition of funds, this role is rarely discussed. METHODS We first differentiated the functions of the regional and central study offices. We then investigated the minimum number of items required and approximate cost of a molecular epidemiology study enrolling 7400 participants from a model region with a population of 100 000 for a 4-year Baseline Survey using a standard protocol developed based on the protocol of Japan Public Health Center-based Prospective Study for the Next Generation. RESULTS The functions of the regional study office were identified, and individual expenses were itemized. The total cost of the 4-year Baseline Survey was 153 million yen, excluding consumption tax. Accounting difficulties in conducting the Survey were clarified. CONCLUSIONS We investigated a standardized example of the tasks and total actual costs of a regional study office. Our approach is easy to utilize and will help improve the management of regional study offices in future molecular epidemiology studies.

validity and reproducibility of a self administered food frequency questionnaire used in the Baseline Survey of the jphc study cohort i
Journal of Epidemiology, 2003Co-Authors: Yoshitaka Tsubono, Minatsu Kobayashi, Satoshi Sasaki, Shoichiro TsuganeAbstract:We examined the validity and reproducibility of a 44-item food frequency questionnaire used in a Baseline Survey of the Japan Public Health Center-Based Prospective Study Cohort I conducted in February 1990. Subjects were 94 men and 107 women selected on a voluntary basis among respondents to the Baseline Survey. Four or five years after the Baseline Survey, they provided four 7-day diet records during a 1-year period, and then responded to the same questionnaire a second time. The median (range) for energy-adjusted correlation coefficients between 30 nutrients measured by the questionnaire and the diet records was 0.36 (0.06-0.81) for men and 0.37 (0.11-0.52) for women. The median correlation (range) for 17 food groups was 0.30 (0.08-0.75) for men and 0.28 (0.08-0.46) for women. The median correlation (range) for energy-adjusted correlation coefficients between the two questionnaires was 0.24 (0.04-0.69) for men and 0.50 (0.27-0.60) for women for the nutrients, and 0.34 (0.15-0.63) for men and 0.48 (0.18-0.55) for women for the food groups, respectively. The results indicate that this brief food frequency questionnaire provides reasonably valid and reproducible measures of consumption for many nutrients and food groups, and is useful for examining the association between diet and health in the Japanese population.J Epidemioil2003;13(Suppl):S125-S133.

Smoking and Drinking Habits among the JPHC Study Participants at Baseline Survey
Journal of Epidemiology, 2001Co-Authors: Tomotaka Sobue, Seiichiro Yamamoto, Shaw WatanabeAbstract:Smoking and drinking habits at Baseline Survey among 110,896 male and female residents aged 40-69 are reported as part of an ongoing prospective population-based cohort in 11 geographically diverse health centers in Japan. The age-adjusted proportion of current and former smokers was 54.8% and 21.8% in males and 8.3% and 2.1% in females, respectively. Mean age at initiation of smoking in males and females was 20.6 and 27.8 years of age, respectively. In males, the age-adjusted proportion of those who drink almost daily was 49.1% and that of those who drink almost never was 19.7%, while in females, it was 5.9% and 71.6%, respectively. When compared by health center, the proportion of male current smokers was lower in Miyako and Ishikawa, both located in Okinawa Prefecture, while in females the proportion was higher in urban areas, such as Katsushika and Suita. The proportion of those who drink almost daily in males was higher in Yokote, Kashiwazaki, Katsushika and Suita, and lower in Ishikawa and Miyako, but in Ishikawa and Miyako, the proportion of those who drink at social events was higher. In females, the proportion of those who drink almost daily was higher in urban areas. There was substantial variation in the types of alcohol beverages consumed by males. In contrast, alcohol consumption in females comprised mainly beer.

Ethiopia Alive & Thrive Baseline Survey 2010: Households
'American Society of Tropical Medicine and Hygiene', 2021Co-Authors: International Food Policy Research InstituteAbstract:This dataset is the result of the household Survey that was conducted to gather data at Baseline as a part of the impact evaluation of the Alive & Thrive (A&T) interventions in Ethiopia. The broad objective of the impact evaluation in Ethiopia is to measure the impact of A&T’s community-based interventions, delivered through the government's health extension program (HEP) platform, in the reduction of stunting and improvement of IYCF practices in two regions where the IFHP operates, namely Tigray and SNNPR (Southern Nations, Nationalities, and People’s Region). A&T is a six-year initiative to facilitate change for improved infant and young child feeding (IYCF) practices at scale in Bangladesh, Ethiopia, and Viet Nam. The goal of A&T is to reduce avoidable death and disability due to suboptimal IYCF in the developing world by increasing exclusive breastfeeding (EBF) until 6 months of age and reducing stunting of children 0-24 months of age. The Ethiopia Baseline Survey had two broad objectives. The first objective was to gather data on the primary impact indicators of the evaluation, prior to implementation of any A&T interventions, to establish a Baseline against which changes would be measured. The second objective was to assess different factors that may influence the outcomes of interest, and thus shape the impact of the primary impact indicators. These factors were determined at five different levels: 1) child, 2) maternal/caregiver, 3) household, 4) community, 5) health care providers, 6) health system. These factors will also provide useful information to interpret the results of the impact evaluation and also signal key issues to pay attention to in the process evaluation. The Ethiopia Baseline Survey used five separate questionnaires that aimed to capture elements along the program impact pathways. These tools include 1) a household questionnaire, 2) a staff questionnaire of HEWs, 3) a staff questionnaire of supervisors of HEWs, 4) a VCHP), and 5) a community questionnaire. The household questionnaire in Ethiopia consisted of 14 different modules covering a wide range of information both for assessing the outcomes of interests as well as factors that influence the uptake and adoption of A&T interventions, such as household food security, socioeconomic status, parental characteristics, maternal knowledge and skills about IYCF, exposure to A&T and other IYCF/nutrition interventions, exposure to media, household gender relationships, and child characteristics, e.g., age, gender, perceptions about size and birth. The questions are largely based on previously validated questions or modules.Alive and Thrive; Open Access; IFPRI1; CRP4PHND; A4NHCGIAR Research Program on Agriculture for Nutrition and Health (A4NH

Bangladesh Alive & Thrive Baseline Survey 2010: Households
'Oxford University Press (OUP)', 2020Co-Authors: International Food Policy Research InstituteAbstract:This dataset is the result of the household Survey conducted to gather data at Baseline as a part of an impact evaluation study of Alive & Thrive (A&T) interventions delivered through Building Resources Across Communities' (BRAC) Essential Health Care (EHC) Program in Bangladesh. The objective of the impact evaluation study is to evaluate the synergistic impact of A&T’s community component along with media communications and private sector activities such as the promotion and integration of micronutrient powders. A&T is a six-year initiative to facilitate change for improved infant and young child feeding (IYCF) practices at scale in Bangladesh, Ethiopia, and Viet Nam. The goal of A&T is to reduce avoidable death and disability due to suboptimal IYCF in the developing world by increasing exclusive breastfeeding (EBF) until 6 months of age and reducing stunting of children 0-24 months of age. In Bangladesh, A&T is working with the government, nongovernmental organizations, and private initiatives to support the implementation of the National IYCF Strategy and Action Plan. The BRAC organization is delivering A&T’s community interventions within its EHC Program and its Maternal, Neonatal, and Child Health (MNCH) Program. BRAC’s frontline health workers, known as Shasthya Shebika and Shasthya Kormi, delivered age-appropriate IYCF counseling and support services during home visits, antenatal and postnatal sessions, and health forums. The Baseline Survey conducted as part of the impact evaluation of A&T interventions delivered through BRAC’s EHC platform had four components—(i) census, (ii) household Survey, (iii) community Survey, and (iv) frontline health workers Survey. The census gathered data on household composition and child age, and was used to generate the sampling frame for the Survey in the selected Survey villages. The household Survey captured the main impact indicators for A&T (WHO-recommended IYCF indicators and child anthropometry), use and exposure to A&T’s intervention platforms, and a variety of other data related to the use of the interventions. This included data on caregiver knowledge and perceptions about IYCF practices, challenges experienced in relation to IYCF practices, caregiver resources (such as education, childcare knowledge, and experience, and physical and mental health) and household resources (such as household composition, socioeconomic status, and food security). The community Survey provided data on key community characteristics such as availability of infrastructure, availability, and access to education, health services, and healthcare providers. The frontline health worker Survey gathered data on service provision by BRAC frontline health workers, traditional birth attendants (TBA), and village doctors. Data were also gathered on health worker time commitment, knowledge and attitude and training related to IYCF, and their job motivation, satisfaction, and supervision. The data included here are from the Survey of households. The Survey was conducted in the 20upazilas across 13 districts in Bangladesh between April and August 2010 by the IFPRI team in collaboration with Data Analysis and Technical Assistance, Ltd.

The IDEFICS cohort: design, characteristics and participation in the Baseline Survey.
International Journal of Obesity, 2011Co-Authors: Wolfgang Ahrens, K Buchecker, Karin Bammann, Antje Hebestreit, Vittorio Krogh, Alfonso Siani, Stefaan De Henauw, Lauren Lissner, Licia Iacoviello, Staffan MarildAbstract:The European IDEFICS (Identification and prevention of dietary- and lifestyle-induced health effects in children and infants) study was set up to determine the aetiology of overweight, obesity and related disorders in children, and to develop and evaluate a tailored primary prevention programme. This paper focuses on the aetiological element of the multicentre study, the measures and examinations, sociodemographic characteristics of the study sample and proportions of participation. Prospective cohort study with an embedded intervention study that started with a Baseline Survey in eight countries in 2007–2008. Baseline participants of the prospective cohort study were 16 224 children aged 2–9 years. Parents reported sociodemographic, behavioural, medical, nutritional and other lifestyle data for their children and families. Examinations of children included anthropometry, blood pressure, fitness, accelerometry, DNA from saliva and physiological markers in blood and urine. The built environment, sensory taste perception and other mechanisms of children's food choices and consumer behaviour were studied in subgroups. Between 1507 and 2567, children with a mean age of 6.0 years and an even sex distribution were recruited from each country. Of them, 82% lived in two-parent families. The distribution of standardised income levels differed by study sample, with low-income groups being strongly represented in Cyprus, Italy and Germany. At least one 24-h dietary recall was obtained for two-thirds of the children. Blood pressure and anthropometry were assessed in more than 90%. A 3-day accelerometry was performed in 46%, motor fitness was assessed in 41%, cardiorespiratory fitness in 35% and ∼11% participated in taste perception tests. The proportion of children donating venous blood, urine and saliva was 57, 86 and 88%, respectively. The IDEFICS cohort provides valuable data to investigate the interplay of social, environmental, genetic, physiological and behavioural factors in the development of major diet- and lifestyle-related disorders affecting children at present.
